What's hot:

Actress Anne Hathaway, who lost 25 pounds on a crash diet for the film, "Les Misérables," looks sporty and sassy in the January 2013 issue of Glamour.

The slender 5-foot-8 Anne dons a white tank top and black underwear that accentuate her lean thighs. Hathaway, 30, admitted she essentially starved herself to look the part of the emaciated Fantine in the tragedy, "Les Misérables."

"I had to be obsessive about it; the idea was to look near death," Hathaway told Vogue. "Looking back on the whole experience, it was definitely a little nuts. It was definitely a break with reality, but I think that’s who Fantine is anyway."

Anne lost 10 pounds before shooting began, and then lost another 15 pounds during a two-week break in filming by eating only two thin squares of dried oatmeal paste a day. Hathaway's competitive personality enabled her to stick to her extreme low-calorie diet.

"I like to fight for a job," she says. "You feel like you've emerged from the scrap, and you're like, 'OK, this one's mine. Did it. Done.' "

Transforming herself physically is nothing new for the dedicated Anne, who worked out five days a week to play Catwoman in "The Dark Knight Rises." In addition to gym workouts, Hathaway underwent stunt training, did strength exercises as well as 90 minutes of dance every day.

Anne, who switched to a vegan diet while training for "The Dark Knight Rises," has really embraced the plant-based eating plan.

"I don't go the soy-meat route; I have a really plant-based diet," she said. "So I wind up cooking at home a lot. Kale is amazing. Spelt [a kind of wheat] pasta is amazing. I can't do the white-flour stuff. It makes me really ill."
